The AirTAC SAI32 Standard Cylinder SAI32BX140S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 140mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAI32X140-S is a double-acting ISO 15552 profile cylinder engineered for compact automation. Delivering 402 N of push force at 0.5 MPa, this 32 mm bore unit is paired with a 140 mm stroke to handle precise mid-range movements. It features an extruded aluminum barrel without tie-rods, ensuring a clean exterior that drops directly into standard ISO 15552 mounting interfaces.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet for use with CMSE or DMSE sensor switches. The barrel incorporates sensor grooves on both sides for flexible switch placement, while fluid connections use PT tapered threads. Adjustable air cushions at both ends protect the end caps from impact during high-speed 30-800 mm/s operations.

Ideal for securing lightweight machined components during secondary milling or drilling operations.
Provides the 402 N push force needed to actuate lightweight routing gates on packaging lines.
The integrated -S magnet works seamlessly with DMSE switches to confirm end-of-stroke positions.
Selecting this 32 mm bore is ideal when your application requires around 402 N of push force at 0.5 MPa. If your load demands less energy, stepping down is not an option in this series, but moving up to a 40 mm bore increases the push force to 628 N at 0.5 MPa for heavier payloads. Because the 140 mm stroke is relatively short, rod-bearing bending is minimal, though external guides should still be used for offset loads.
As a true ISO 15552 profile cylinder, this model serves as a seamless dimensional replacement for competing standard cylinders. To match this exact configuration, specify the 32 mm bore, 140 mm stroke, PT port thread, and the -S magnet option. Remember that the standard double-acting design relies on continuous air pressure; if pneumatic supply drops, the piston will drift. For applications requiring dead-stop holding without air, consider the SAIL locking variant.
Quick checklist
At 0.5 MPa operating pressure, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
Yes. The SAI32X140-S is built to standard ISO 15552 mounting dimensions, allowing it to serve as a direct replacement for other profile cylinders of the same bore and stroke, using PT tapered ports.
